Francisella-Like Endosymbiont Detected in Haemaphysalis Ticks (Acari: Ixodidae) From the Republic of Korea

J Med Entomol. 2017 Nov 7;54(6):1735-1742. doi: 10.1093/jme/tjx123.

Abstract

A total of 6,255 ticks belonging to three genera and six species (Haemaphysalis flava Neumann, Haemaphysalis longicornis Neumann, Haemaphysalis phasiana Saito, Ixodes nipponensis Kitaoka & Saito, Ixodes persulcatus Schulze, and Amblyomma testudinarium Koch) collected from May-August, 2013, at four southwestern provinces in the Republic of Korea (ROK) were submitted to the Armed Forces Research Institute of Medical Sciences and assayed for selected tick-borne pathogens. One pool each of H. flava and H. phasiana was positive by PCR and sequencing for a Francisella-like endosymbiont, while all pools were negative for Francisella tularensis, the causative agent of tularemia.

Keywords: Francisella tularensis endosymbiont; Haemaphysalis flava; Haemaphysalis phasiana; Korea; tick surveillance.
